Apparatuses, systems, and methods for a wireless device to perform a method including performing one or more of periodic beam quality measurements and/or event based beam quality measurements, determining, based at least in part on one or more of the periodic beam quality measurements and/or the event based beam quality measurements, a recommended beam quality measurement configuration, and transmitting, to a base station serving the UE, the recommended beam quality measurement configuration. In addition, the UE may perform receiving, from the base station, instructions regarding the beam quality measurement configuration. The instructions may include instructions to activate, deactivate, and/or modify at least one beam quality measurement configuration. In addition, the instructions may be based, at least in part, on the recommended beam quality measurement configuration.

2. The UE of claim 1 , wherein the instructions further comprise second instructions to deactivate at least one beam quality measurement configuration.
3. The UE of claim 1 , wherein the instructions further comprise second instructions to modify at least one beam quality measurement configuration.
4. The UE of claim 1 , wherein the one or more beam quality measurements are with respect to at least one of: channel state information reference signals (CSI-RS); and synchronization signal blocks (SSBs).
5. The UE of claim 1 , wherein determining the recommended beam quality measurement configuration is further based, at least in part, on conditions at the UE.
6. The UE of claim 5 , wherein the conditions comprise at least one of: Doppler shift; Doppler spread; motion detection; rotation detection; change of L1-RSRP; trend of L1-RSRP; or blockage of antenna of the UE.
7. The UE of claim 1 , wherein, to transmit the recommended beam quality measurement configuration, the one or more processors are further configured to transmit the recommended beam quality measurement configuration via a medium access control (MAC) control element (CE), a short physical uplink control channel (PUCCH) message, or radio resource control (RRC) message.
8. The UE of claim 1 , wherein performing the one or more beam quality measurements is responsive to detection of an event.
9. The UE of claim 8 , wherein the event comprises at least one of: detection of a strongest beam among a group of monitored beam pair links exceeding a threshold; detection of the strongest beam among the group of monitored beam pair links is dropping below the threshold; detection of all monitored beam pair links becoming weaker than the threshold; detection of neighbor beams that are better than a threshold for a time-to-trigger (TTT) time; detection of a serving beam being worse than a first threshold and a neighbor beam exceeding a second threshold for a time hysteresis TTT; detection of a serving beam quality continuously reducing in a last first specified number of configured measurement cycles with stepsize more than the first threshold and neighbor beam quality continuously increasing in a last second specified number of configured measurement cycles with stepsize more than the second threshold; or detection of un-symmetric uplink and downlink beams based on uplink quality as observed at the UE.
10. The UE of claim 1 , wherein the recommended beam quality measurement configuration comprises one of: a periodic measurement configuration index; and a set of measurement parameters associated with the recommended beam quality measurement configuration.
11. An apparatus, comprising: a memory; and a processor in communication with the memory, wherein the processor is configured to: perform one or more beam quality measurements, wherein the one or more beam quality measurements comprise at least one of a periodic beam quality measurement and an event-based beam quality measurement; determine, based at least in part on the one or more beam quality measurements, a recommended beam quality measurement configuration; generate instructions to transmit, to a base station serving a wireless device associated with the apparatus, the recommended beam quality measurement configuration; and receive, from the base station, instructions regarding the recommended beam quality measurement configuration, wherein the instructions comprise first instructions to activate at least one beam quality measurement configuration, wherein the instructions are based, at least in part, on the recommended beam quality measurement configuration.
12. The apparatus of claim 11 , wherein the instructions further comprise second instructions to deactivate at least one beam quality measurement configuration.
13. The apparatus of claim 11 , wherein the instructions further comprise second instructions to modify at least one beam quality measurement configuration.
14. The apparatus of claim 11 , wherein the one or more beam quality measurements are with respect to at least one of: channel state information reference signals (CSI-RS); and synchronization signal blocks (SSBs).
15. The apparatus of claim 11 , wherein determining the recommended beam quality measurement configuration is further based, at least in part, on conditions at the wireless device.
16. The apparatus of claim 11 , wherein, to generate instructions to transmit the recommended beam quality measurement configuration, the processor is further configured to generate instructions to transmit the recommended beam quality measurement configuration via a medium access control (MAC) control element (CE), a short physical uplink control channel (PUCCH) message, or radio resource control (RRC) message.
17. A non-transitory computer readable memory medium storing program instructions executable by processing circuitry to cause a user equipment device (UE) to: perform one or more beam quality measurements, wherein the one or more beam quality measurements comprise at least one of a periodic beam quality measurement and an event-based beam quality measurement; determine, based at least in part on the one or more beam quality measurements, a recommended beam quality measurement configuration; generate instructions to transmit, to a base station serving the UE, the recommended beam quality measurement configuration; and receive, from the base station, instructions regarding the recommended beam quality measurement configuration, wherein the instructions comprise first instructions to activate at least one beam quality measurement configuration, wherein the instructions are based, at least in part, on the recommended beam quality measurement configuration.
18. The non-transitory computer readable memory medium of claim 17 , wherein the instructions further comprise second instructions to deactivate at least one beam quality measurement configuration.
19. The non-transitory computer readable memory medium of claim 17 , wherein the instructions further comprise second instructions to modify at least one beam quality measurement configuration.
